Proposed OCCC – Preliminary Engineering Report iv
Oahu Community Correctional Center October 2017
EXECUTIVE SUMMARY
The State of Hawaii Department of Public Safety (PSD) is responsible to provide a safe, secure, and
humane environment for the care and custody of adult male and female offenders originating from the
Island of Oahu. The current Oahu Community Correctional Center (OCCC) is out of date, inefficient and
no longer meets the needs of PSD. On behalf of PSD, the State of Hawaii Department of Accounting and
General Services (DAGS) is proposing to develop a replacement facility for the existing OCCC facility in
Kalihi, Oahu, Hawaii. Four (4) alternative sites on Oahu are under consideration for replacement of the
existing OCCC, identified as follows.
- Existing OCCC site in Kalihi;
- Animal Quarantine Station in Halawa;
- Halawa Correctional Facility in Halawa; and
- Mililani Technology Park Lot 17 in Mililani

Each alternative would include relocating female inmates currently housed at OCCC to the existing
Women‘s Community Correctional Center (WCCC) in Kailua.
This preliminary engineering assessment was conducted to provide a detailed evaluation of four (4)
alternative sites related to the civil infrastructure and utility systems for the replacement of the OCCC.
The objective of the report is to review the existing site infrastructure improvements, determine the project
requirements related to the roadway and parking facilities, site grading, storm drainage system, sanitary
sewer system and water system, and, based on the project requirements, determine required
improvements, and identify possible opportunities and constraints for the OCCC replacement facility.
An Environmental Impact Statement is being prepared to assess each alternative site and determine
which site is most feasible for development of the replacement for the existing OCCC facility.
